My point is not/was not to 'dis' drones, just to caution that some are raising their expectations of these mobile cameras way above their current capabilities.
As you say they are great for such as SAR, Electrical Grid inspections, road and bridge inspections, cell tower inspections, building safety surveys etc.
Unfortunately - and there is significant evidence of it in the USA - organisations are shutting down aircraft operations in favour of drones apparently in the belief that the service will be the same.
